In ancient China, the emperor decrees that one man from each family must serve in the Imperial Army to defend the country from Northern invaders led by a fearsome warrior. Mulan, the eldest daughter of an honored warrior, steps in to take the place of her ailing father. Masquerading as a man and embracing the name Hua Jun, she is tested every step of the way and must harness her inner-strength to embrace her true potential. Mulan's journey of self-discovery transforms her into an honored warrior but calls for significant personal sacrifice.

As she strives for the respect of her comrades and superiors, Mulan's skills are quickly recognized, and she rises through the ranks. However, her heroic actions spark suspicion and threaten exposure. Throughout her perilous quest, she comes face-to-face with the Northern invaders and a formidable witch, whose allegiance is uncertain. As Mulan attempts to keep her identity hidden, the values of courage, family, and honor are severely tested in the impending confrontation that will determine the fate of her family and her country.
